In this paper study the microstructure of wave self-propagating high-temperature synthesis (SHS) to find relationship between rate reaction front, characteristic size foci and combustion temperature. Measure dynamics temperature field SHS process was carried out using original optical complex micropyrometer with a spatial resolution 5.9 mkm speed recording up 10,000 frames per second. A method analysis thermal data implemented on basis ergodic model regime MATLAB. experiment is varied...
State of the art line powder metallurgy is application initial powders as micro-composites with additional components - premixes. Usage premixes inhibits segregation added and implies homogeneity charge composition, finally it has a significant impact on structure formation properties end products. The aim present work was to design new production technology based iron which layer-by-layer plated by aluminium copper. We propose carry out Cu-Al-Fe in two stages: cladding coating obtained...
The burned pellets must retain the strength from time they come off roasting machine until are loaded into blast furnace. One indicator of is compressive strength, i.e., maximum applied load at which iron-ore pellet completely collapses. paper studies character destruction titanomagnetite fraction 10 - 16 mm in static compression test according to Russian State Standard 24765-81. It shown that main type during emergence and development plane cracks passing through center magnetite core,...
The effect of sintering on the mechanical properties iron-based vanadium-containing powders with various additives is studied.The results uniaxial compression testing show that specimens made powder without and compositions zinc or copper change their shape from cylindrical to barrel-type increasing pressure, whereas less dense phosphorus collapse.The graphite as an additive remains unchanged.After sintering, Brinell hardness for iron decreases, it increases those graphite, particularly...
A technology was developed for the formation of a multilayer composite coating obtained by sub – and supersonic plasma spraying method based on Al, Ti, Ni, Mo. The results investigation Al-Ti-Ni-Mo powder are deposited subsonic deposition steel substrate followed application an anticorrosion from paint material (PCM) CINEP brand, which is protected Al-Ti-Ni-Mo. This layer designed to protect anticorrosive layers main multicomponent products, can be subjected external mechanical stress during...
Features of phase formation during the aluminothermal reduction titanium from their dioxide were studied using methods thermodynamic modeling, X-ray and electron microprobe analysis. The interaction aluminum with proceeds through stage monoxide formation. It is characterized by TixAIy intermetallides different composition (TiAl3, TiAl, Ti2Al) depending on ratio Al TiO2.
Influence of basicity on viscosity, crystallization onset temperature, phase composition, and structure slags the СаО – SiO 2 18 % Cr O 3 6 B Аl 8 МgO system in range ( = CaO/SiO ) from 1.0 up to 2.5 was studied using vibrational viscometry, thermodynamic modeling, Raman spectroscopy. It established that physical properties depend balance polymerization degree composition. Acid with a belong category “long” are characterized by an increased proportion high-temperature phases 34.1 %. However,...
The authors studied the physicochemical characteristics of new complex alloys containing, %: 11 – 30 Nb, 23 28 Si, 3 10 Al and 4 Ti. It was shown that have most favorable values density crystallization temperatures compared to standard ferroniobium (60 wt. % Nb). Complex with a low concentration niobium acceptable optimal (5740 6560 kg/m ). This allows pieces ferroalloy be completely in liquid steel when it is released into ladle, constantly motion, which increases absorption leading...
The questions of oxidizing roasting iron ore raw materials with production sinter and pellets are considered. question reduction is studied. Phase transformations regenerative Features phase containing titanium discussed. reducibility, durability temperatures softening melting metallurgical studied In Vitro . effect the burned on compression also defined.
The paper provides an overview of modern methods for studying the dynamics structure formation materials. analysis possibilities dynamic electron microscopy and optical controlling structural-phase state materials in high-temperature fast-flowing processes is carried out. Methods pyrometry field SHS, gas-thermal spraying coatings, additive synthesis metal ceramic products are considered. A review a new non-contact method measuring temperature spectral degree blackness presented. results...
